1 378 618 Specification of Letters Patent. Patented M Application filed April 28, 1920. Serial No. 377,386.

T 0 all whom it may concern:

. Be it known that I, CHARLES H. ROBBINS, a citizen of the United States of America, and a resident of Gleasondale, in the county of Middlesex and Commonwealth of Massachusetts, have invented certain new and useful Improvements in Apparatus forDyeing, of which the following is a specification.

This invention relates to an apparatus for dyeing and has for its object the production of a mechanism whereby a uniform color to the wool or other material submerged in the dye liquor may be quickly obtained.

The invention consists in an apparatus for pumping the dye liquor from the bottom of the dye vat and through a system of pipes into a revoluble spraying device within the vat and positioned above the wool or other material submerged in the dye liquor.

The inventlon further consists 1n prov1ding a revoluble hollow head having a plu-' rality of perforated tubular members radiating therefrom. and closed at their outer ends.

ing means whereby these radiating tubular members may be adjusted about their axes.

The invention further consists in provid ing the revoluble head with radiating tubu lar members thebore at the outer end of each of which is considerably less in diameter than the bore at the inner end.

The invention further consists of certain novel features of construction and arrangement of parts which will be fully understood by reference to the description of the drawings and to the claims to be hereinafter given.

For the purpose of illustrating the inven tion, one preferred form thereof is illustrated in the drawings, this form having been found to'give'satisfactory and reliable results although it is to be understood that the various instrumentalities of which the invention consists can'be variously arranged and organized and the invention is not limited to the precise arrangement and organization of these instrumentalities as herein shown and described, except as required by the scope of the appended claims. In the drawings:

Figure 1 represents a section of a dyeing 3 vat showing in'elevation an apparatus coactmg therewith and embodying the principles of the present invention.

Fig. 2 represents a plan of the vat with the spraying device contained therein.

F 1g. 8 represents a Vertical section of'a portlon of the spraying device, drawn to an enlarged scale, and

Fig. 4 represents a Section of the same on line 4, 4, on F 1g. 3.

Similar characters indicate like parts throughout theseveral figures of the drawmgs.

In the drawings, 10 is a flooring or other support having superimposed thereon blocks 11 on which is positioned a dye vat l2 havmg. the usual perforated false bottom 13 for the support of the wool or other material which it is desired to dye.

From the lower end of the vat 12 extends an outlet pipe 14 to a T 15 supported upon a foundation 16.

From one branch of the T 15 extends a p1pe17 having a valve 18 therein From another branch of said T 15 extends a pipe 1.9 communicating with a centrifugal pump 20 having an outlet branch 21 communicating with a vertical pipe 22.

At the upper end ofthe vertical pipe 22 1s a swing oint 23 having a horizontal pipe 2 1 extending therefrom, Said horizontal pipe 24 having a downward branch 25 on the lower end of which is mounted the revoluble spraying device 26. y

The horizontal pipe 24 has secured thereto, a collar 27 from which extends a cable or cord 28 passing over a sheave or block 29. By means of this cord 28 the horizontal pipe 24: with the spraying device 26 on its branch 25 may be raised into the position shown in dotted lines in Fig; 1 of the drawings thereby givmg free access to the vat 12.

The pump '21 is actuated by means of a shafti-BO driven by a steam turbine 31 to which Steam may be admitted through the pipe 32, said steam being exhausted through the pipe 33.

The pump 20 and the steam turbine or other motor 31 may be of any usual confrom through the pipes 19, 22, '24: and 25 into the spraying device 26 and'therefrom onto the material submerged in the liquor within said vat 12.

iVhen the dye liquor is being thus circulated by means of the pump 20, the valve 18 is closed.

When it is desired to draw off the dye liqand upon these balls is positioned another annular groove plate 38.

On the upper surface of the plate 38 rests the cap 89 of the revoluble hollow head 40.

This head 40 has a plurality of inwardly extending hubs 41 into each of which is screwed a tubular member 42.

Each of these members 42 is provided with a flat-sided portion 43 by which said tubular member 42 may be moved about its axis.

To the outer end of each tubular member 42 is threaded a union 44 having extending outwardly therefrom a tubular member 45 the bore of which is considerably less in diameter than the bore of the member 42.

The outer end of each tubular member 45 is closed by a cap 46.

Each of the tubular members 42 and 45 is provided with a plurality of perforations 47 through which the liquor pumped into the interior of the head 40 may be forced outwardly upon the upper surface of the liquor within the vat 12.

The head40 is freely revoluble about the axis of the branch pipe 25 and the openings 47 in the tubular members 42, 45 are located at an angle to the upper surface 48 of the liquor within the vat 12 as indicated in dotted lines in Fig. 4 of the drawings.

As the liquor is ejected through these perforations 47 and strikes the upper surface 48 of the liquor within the vat 12, the head 40 will be caused to rotate about the axis of the branch pipe 25 on the lower end of which said head 40 is mounted.

The plurality of streams of liquor ejected through the said openings 47 in the various tubular members 42 and 45 will effect the rotation of the head 40 and by varying the angle of these discharge openings 47 relatively to the upper surface of the liquor within the vat 12, the speed of rotation of the head 40 may be varied as desired.

As the various streams of liquor passing through the system and ejected through the openings 47 comes into contact with the dye liquor and material submerged therein, the action of said streams of liquor will cause said liquor to be circulated spirally therein and insure its contact with every part of said material thus producing a uniform color throughout the entire mass of wool or other material contained within the vat.

Above the head 40 and secured to the branch pipe 25 is a deflector or hood 49 against which any liquor escaping upwardly from the upper end of the head 40 will strike and be deflected downwardly into the vat 12. i

It it obvious that in case the head 40 rotates too rapidly the speed may be reduced by adjusting the members 42 so that the angle of the jets of liquor passing therefrom will be more nearly perpendicular to the upper surface 48 of the dye liquor within the vat 12. 7

By reducing the bore in the tubular members 45irelatively to the bores of the tubular members 42, means are provided whereby the jets of liquor forced downwardly through the perforations 47 in the tubular members 45 will have more force than the jets of liquor projected through the perforations 47 in the tubular members 42.

This apparatus is simple in construction, very effective in its operation and quickly produces a uniform colorthroughout wool or other material submerged in the liquor within the dye vat.

It is believed that with the foregoing explanation, the operation and many advantages of the invention will be fully understood without further description.

Having thus described my invention, I claim:

The combination with a dye-vat having a perforated false bottom; a circulating pipe for the dye liquor having a branch extending downwardly into saidvat; and a spraying device freely revoluble about the lower end of said branch pipe above the liquor and provided with means for ejecting jets downwardly onto said liquor and at an angle thereto.
